"She's too dope for you 2 understand!" Kardashian tweeted to her 9.21 million followers of her 18-year-old sibling, who was nearly unrecognizable on the runway at Marc Jacobs' show. "Yall would trade places with her in a second. The hate is real! Lol bye haters!"

Then, to really drive the point home, she added, "Basic bitches NOT wanted." (Jenner retweeted the message to her own followers, but has not otherwise acknowledged the criticism.)

Jenner, for her part, told Into the Gloss before the show that she was excited to strut her stuff. "I just recently turned 18, so this [Marc Jacobs show] is my big kick-off to start and grow my career," she said.

"The New York fashion scene is crazy, madness, but I love the energy. I love everything about it -- like the hair and makeup today, it's incredible," she gushed. "I've never had my eyebrows bleached; I don't even look like myself!"
